About

My research aims to understand how technology can help solve social problems. Much of my work focuses on the environmental and human health consequences of energy production and use. I employ quantitative decision analysis, buttressed by qualitative insight, to understand how economic, political, and operational realities constrain technology deployment. 

I focus on finding strategies to decarbonize the economy, and to adapt to the warming that has and will occur even if we cut greenhouse gas emissions very rapidly. I am particularly interested in finding ways to make both mitigation and adaptation equitable. My projects fall into two broad categories:

  • The environmental consequences of electrification, and
  • The consequences of automation for the environment, equity, and work

    • Notable paper: This paper explores the question of whether it is possible, in the medium term, to make light vehicles both autonomous and electric. It uses first-principles energy modeling to conclude that the energy penalty associated with automation will likely not exceed 15% of the range of electric vehicles currently on the market. It then advances a series of economic arguments that use customers’ revealed preferences to suggest that travelers will value autonomy more than they do this loss of range. The paper won the Herb Toor Award at EPP for Best Qualifier paper for my doctoral student Aniruddh Mohan.

    • Notable paper: This paper shows that the economics of distributed metal additive manufacturing (AM) are preferable to centralized additive manufacturing in only a limited set of circumstances. In some cases, political support for AM is based partially on the assumption that the technology will foster the localization of manufacturing. Some analysts speculate that AM will reduce the need for freight and contribute to reducing greenhouse gas emissions. This paper suggests that such expectations are overblown.

    • Notable paper: This paper demonstrates an approach to help analysts to estimate the extent to which public fear of a technology might constrain its development. For controversial technologies like nuclear power, modelers typically evaluate two extreme but unrealistic scenarios: one, where the technology is deployed to the extent that is economically optimal, and two, where the controversial technology is completely excluded. We show that it is possible for modelers to improve on this approach by estimating the extent to which a public will allow the deployment of a technology, given the public’s anxieties about it.
